Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] At present, there are many beverage processing equipment such as kettles, coffee machines and milk tea machines on the market that have heating function and instant heating function, which can instantly heat beverages; generally, beverage processing equipment with instant heating function basically includes an inner tank, a heating wire and an instant heating pipe, the heating wire is attached to the instant heating pipe, and the instant heating pipe connects the inner tank with the water outlet pipeline of the beverage processing equipment; when the user uses the instant heating function of the beverage processing equipment, the heating pipe is powered on and heated, and then the heat is transferred to the instant heating pipe, and the liquid in the instant heating pipe absorbs heat to complete the heating process of the beverage.

[0037] In order to reduce the volume of beverage processing equipment while retaining the heating function and instant heating function, the heating wire is generally set on the instant heating pipe, the instant heating pipe is connected to the inner tank and the water outlet pipe, and the instant heating pipe and the heating wire are both attached to the bottom of the inner tank of the beverage processing equipment, thereby reducing the overall volume of the beverage processing equipment. However, the above arrangement method will cause a considerable part of the heat generated by the heating wire to be transferred to the instant heating pipe, and then transferred to the inner tank through the instant heating pipe, resulting in a low efficiency of heat transfer to the inner tank, which in turn leads to a slow heating rate of the inner tank.

[0038] Reference Figures 1 to 8 In order to solve the above problems, the utility model proposes a liquid heating container, including an inner tank 400, a heating element 200 and a water pipe 100; wherein the inner tank 400 is used to contain liquid, the water pipe 100 is connected to the bottom of the inner tank 400, and the heating element 200 is used to heat the water pipe 100; when the heating element 200 heats the water pipe 100, the liquid in the water pipe 100 will be heated and vaporized, thereby generating steam, and the steam will move to the bottom of the inner tank 400 through the water pipe 100 under the action of buoyancy and enter the inner tank 400, and then will further evaporate under the action of buoyancy. Float toward the liquid surface; the steam itself has a high heat content, so the steam will exchange heat with the liquid in the inner tank 400 during the floating process, thereby completing the heating of the liquid in the inner tank 400; and during the floating process of the steam, the liquid in the inner tank 400 will be continuously stirred, so that the heat energy of the liquid in the inner tank 400 will be more uniform; thus, the heating element 200 can be used to heat the water pipe 100 to generate steam, and then the steam can be used to heat the inner tank 400, thereby accelerating the heat transfer efficiency and further improving the heating rate of the inner tank 400.

[0039] It should be noted that, during the process of generating steam, the water pipe 100 is only connected to the inner tank 400, thereby ensuring that the steam generated by the heating of the water pipe 100 will not leak out and cause heat loss; and the water pipe 100 is connected to the bottom of the inner tank 400. When steam is generated in the water pipe 100, the volume of the liquid in the water pipe 100 will decrease, and the liquid in the inner tank 400 will flow into the water pipe 100 under the action of gravity, thereby replenishing the liquid in the water pipe 100, so that the water pipe 100 can continuously generate steam after being heated, and can continuously heat the liquid in the inner tank 400.

[0040] Since the water pipe 100 has a higher temperature after being heated by the heating element 200, and its temperature is greater than the temperature required for water vaporization, and the water pipe 100 is attached to the bottom of the inner pot 400, the heat on the outer surface of the water pipe 100 can be transferred to the inner pot 400 through the bottom of the inner pot 400 to heat the liquid in the inner pot 400; but such a transfer process will cause the bottom of the inner pot 400 to be heated unevenly, which is not conducive to the heating of the liquid; therefore, a heat transfer aluminum plate 300 is provided on the bottom of the inner pot 400, and the water pipe 100 is provided on the bottom surface of the heat transfer aluminum plate 300, and the heat of the water pipe 100 can be transferred to the bottom of the inner pot 400 through the heat transfer aluminum plate 300, so that the bottom of the inner pot 400 can be heated more evenly, so that the liquid in the inner pot 400 can be better heated, and the heat generated by the heating element 200 can be maximized.

[0041] Reference Figures 2 to 5 Specifically, the heat transfer aluminum plate 300 is fixedly connected to the bottom of the inner tank 400, and the water pipe 100 has a metal outer layer, which is convenient for the water pipe 100 to absorb and transfer the heat from the heating element 200 and also convenient for processing the water pipe 100. The heating element 200 also has a metal outer layer that is convenient for heat transfer and processing; further, the water pipe 100 has an aluminum outer layer, and aluminum has good heat conduction efficiency; the water pipe 100 is welded to the heat transfer aluminum plate 300, the heating element 200 is fixed to the water pipe 100, and the heat transfer aluminum plate 300 is welded to the bottom of the inner tank 400; the welding processing method can make full use of the metal properties between the components, that is, welding is one of the common methods for fixing metal components and metal components, and welding can make the metal components tightly connected together, thereby facilitating heat transfer and improving heat conduction efficiency; therefore, welding will further accelerate the process of transferring the heat generated by the heating element 200 to the inner tank 400, and further improve the heating rate of the inner tank 400.

[0042] It should be noted that, in this embodiment, in order to make the water in the water pipe 100 vaporize faster, that is, in order to further increase the upper temperature limit that the water pipe 100 can reach, the water pipe 100 has a certain length so that the water pipe 100 can be spirally arranged on the heat transfer aluminum plate 300, so that the heating time of the water in the water pipe 100 is extended, and then the water in the water pipe 100 can obtain more heat and have a higher temperature.

[0043] Further, in the present invention, the heating element 200 can be a heating tube or a heating film, and both the heating tube and the heating film can heat the water pipe 100; Figures 2 to 5 In order to achieve a good heating effect for the spirally arranged water pipe 100, that is, when the water flows in the water pipe 100, the water can be heated and absorb heat all the time, the heating element 200 in this embodiment adopts a heat pipe, and the diameter of the heating element 200 is larger than the diameter of the water pipe 100; since the water pipe 100 is spirally arranged, the contact surface 210 between the heating element 200 and the water pipe 100 is increased, thereby improving the heat transfer efficiency between the heating element 200 and the water pipe 100; in the actual application process, that is, in unit time, after being heated by the heating element 200, the water in the water pipe 100 can reach a higher temperature, that is, the heating effect of the heating element 200 on the water pipe 100 is improved.

[0044] In this embodiment, in order to better transfer the heat generated by the heating element 200 to the water pipe 100, a contact surface 210 is provided on the heating element 200, and the water pipe 100 is connected to the contact surface 210; specifically, the outer layer of the water pipe 100 is wrapped with aluminum, which is a good heat transfer material, and the heating element 200 is made of metal, so the outer layer of the water pipe 100 can be directly welded to the heating element 200, so that when the heating element 200 is powered on and generates heat, the heat can be directly transferred to the water pipe 100. Furthermore, the contact surface 210 provided on the heating element 200 facilitates the welding of the water pipe 100 to the heating element 200 during installation, thereby improving the convenience of the overall structure during assembly; and the provision of the contact surface 210 can increase the contact surface area 210 after the heating element 200 and the water pipe 100 are welded, so as to facilitate better heat transfer.

[0045] Reference Figures 2 to 5It should be noted that, in order to make the heating element 200 have a contact surface 210, in the present embodiment, the heating element 200 is annular and has a notch, and an electrode can be installed at the notch to connect the circuit, so that the heating element 200 can generate heat by using the current; and the cross section of the heating element 200 perpendicular to its extension direction is a quadrilateral, so that the heating element 200 can be set to have one side as the contact surface 210, which is convenient for welding the water pipe 100 to the heating element 200. Further, the heating element 200 can be square, rectangular, rhombus or trapezoidal. In this embodiment, in order to maintain the volume of the heating element 200, that is, to maintain the heating effect of the heating element 200, and at the same time to maximize the contact surface 210 area between the heating element 200 and the water pipe 100, the cross section of the heating element 200 perpendicular to its extension direction is a trapezoid, and the lower bottom surface of the trapezoid is the contact surface 210 of the heating element 200. The trapezoidal setting enables the heating element 200 to have a larger contact surface 210 area with the water pipe 100 without reducing the volume, so that while ensuring the heating effect of the heating element 200, it can maximize the It is possible to improve the heat transfer effect between the heating element 200 and the water pipe 100; and in order to make the heating element 200 have the largest contact surface 210 while ensuring the compatibility between the heating element 200 and other structures, the cross-section of the heating element 200 perpendicular to its extension direction is an isosceles trapezoid, so that the heating element 200 can have the largest contact surface 210 (that is, the lower bottom surface of the cross-section of the heating element 200) while also having a mounting surface that is compatible with other structures (that is, the upper bottom surface of the heating element 200), and then the heating element 200 can have a mounting surface that is compatible with other structures after installation, so that the heating element 200 is not easy to shake after installation and matching with other structures, thereby improving the stability of the heating element 200; and the setting of the mounting surface facilitates the insulation of the heating element 200, thereby improving the stability of the heating element 200 while reducing the possibility of direct contact between the heating element 200 and other structures during use, thereby reducing the possibility of other structures contacting with the high-temperature heating element 200 and melting or even catching fire, further improving the safety of the overall structure.

[0046] Based on the above description, in the present invention, in order to make the liquid heating container proposed in the present invention have an instant heating function, the liquid heating container proposed in the present invention also includes a water outlet pipe 500, and the water outlet pipe 500 is communicated with the water pipe 100, so that the water heated by the water pipe 100 can be directly discharged through the water outlet pipe 500, thereby completing the instant heating function of the liquid heating container.

[0047] The liquid heating container proposed in the utility model includes a main body, in which a heating chamber for accommodating an inner tank is formed, and the inner tank is detachably arranged in the heating chamber; due to the arrangement of the inner tank, the water pipe and the heating element are also arranged in the heating chamber.

[0048] In combination with the above description, in order to enable the water outlet pipe 500 to discharge water smoothly, a water pump 600 is arranged on the bottom of the inner tank 400, and the two ends of the water pump 600 are respectively connected to the inner tank 400 and the water pipe 100, so that the water pump 600 will pump the water pump 600 into the water pipe 100, and the water pipe 100 is connected to the water outlet pipe 500, and then the water pump 600 can pump the water pump 600 into the water outlet pipe 500 to complete the water outlet, that is, the water pump 600 can provide power for the water outlet of the instant heating function of the liquid heating container.

[0049] However, it should be noted that since the water pump 600 is arranged at the bottom of the inner pot 400 and the water pump 600 is connected to the water pipe 100, the water pump 600 is actually located between the water pipe 100 and the inner pot 400; in the instant heating function mode of the liquid heating container, the heating element 200 heats the water pipe 100, and steam is generated inside the water pipe 100. The steam will return to the inner pot 400 through the water pump 600, that is, the water pump 600 will not hinder the reflux of steam.

[0050] In this embodiment, the water pump 600 can be in the form of an impeller pump, and the water pump 600 is not limited to an impeller pump. In order to install the water pump 600, a mounting hole 310 is provided on the heat transfer aluminum plate 300, and the mounting hole 310 is used to make way for the installation of the water pump 600; specifically, the water inlet end of the water pump 600 can be connected to the inner tank 400 through the mounting hole 310, or an interface can be provided on the bottom of the inner tank 400, and the water pump 600 is connected to the interface in the mounting hole 310.

[0051] However, it should be noted that the installation location of the water pump 600 is not limited to the bottom of the inner tank 400, and can also be installed in other locations as long as it can provide power for the entire water channel.

[0052] Accordingly, in order to ensure that the steam generated in the water pipe 100 does not overflow through the water outlet pipe 500 in the instant heating mode, but returns to the inner tank 400, a water outlet valve 700 is provided in the water outlet pipe 500 in the embodiment of the utility model; in the heating mode, the water outlet valve 700 cuts off the connection between the water outlet pipe 500 and the water pipe 100, so that the steam generated in the water pipe 100 can only flow back into the inner tank 400 and cannot overflow through the water outlet pipe 500; and in the instant heating mode, the water outlet valve 700 opens the connection between the water outlet valve and the water pipe 100, and the liquid heated by the water pipe 100 can be discharged through the water outlet pipe 500.

[0053] In this embodiment, the water outlet valve 700 is a solenoid valve, but is not limited to a solenoid valve.

[0054] In combination with the above, the liquid heating container proposed in the utility model can generate steam in the water pipe 100, that is, the water pipe 100 can gather more heat generated by the heating element 200, that is, the upper limit of the temperature that the water pipe 100 can heat can be increased, or in other words, at the same set temperature, the time required for the water pipe 100 to heat water to the set temperature can be reduced.

[0055] Reference Figure 7 and Figure 8 In order to ensure the normal use of the heating function, the water pipe 100 can be used to heat the inner pot 400 as a whole; that is, in the heating mode, the heating element 200 also heats the water pipe 100, but the water pipe 100 does not discharge water at this time; due to the high temperature generated by the heating pipe, the water pipe 100 will also have a high temperature, which can exceed the boiling point of water, so that the water in the water pipe 100 will form steam, and the steam will return to the inner pot 400 through the water pipe 100, thereby stirring the water in the inner pot 400 that heats up slowly, and the stirring process of the steam The steam will exchange heat with the water in the inner pot 400, and the inner pot 400 is generally sealed during the heating process, so that the steam will cause the water in the inner pot 400 to heat up, and the stirring effect of the steam on the water in the inner pot 400 will also accelerate the heat transfer, so that the water in the inner pot 400 can heat up quickly; at the same time, the heat on the water pipe 100 will be transferred to the heat transfer aluminum plate 300 via the heat conduction structure, and the heat transfer aluminum plate 300 will transfer the heat to the inner pot 400 to further heat the inner pot 400; this arrangement can maximize the use of heat.

[0056] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
